# Expert Tips:

01 -
  • It tastes like proper tacos without the guilt or the carb crash afterward.
  • The whole thing comes together in less time than it takes to order takeout, yet feels restaurant-worthy when it comes out of the oven.
  • Leftovers actually improve by the next day as flavors settle and meld together.
02 -
  • If your cauliflower rice is frozen, thaw it completely and squeeze out as much moisture as possible, or your casserole will end up watery and sad.
  • Don't skip draining the canned tomatoes—that extra liquid is sneaky and will make your whole dish soggy by the next day.
03 -
  • If you're meal prepping, assemble the casserole in the dish, cover it, and refrigerate overnight—it actually bakes better when everything has time to get acquainted before heat hits it.
  • Double the recipe and freeze half unbaked, then you can pop it straight from freezer to oven on a night when cooking feels impossible.
